T o all whom t may concern:

Be it known that l, JOHN B. Pase/rrr., a citizen ot the United States, residing at Snyder, in the county ot Scurry, State of TeXas, have invented certain new and useful Improvements in Stovepipe-Drums; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to stove pipe drums and its principal object is to improve the general construction et devices of this character so that they may be both readily cleaned and that the temperature of the inner drum may be regulated.

With the above and other objects in view, the invention consists in general of a device of this kind includingl an inner drum, an outer drum and certain other features of novel and improved construction.

The invention further consists in certain novel. details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically set forth in the claims.

ln the accompanying' drawings, like characters of reference indicate like parts in the several views, and -Figure 1 is a longitudinal section through a drum constructed in accordance with this invention. Fig. 2 is a view of the baek end of such a drum, Fig. 3 is a view of the front end of the drum, the 5 door being open and partially broken away. The invention consists in an outer drum having a liXed back head 11 secured thereto and this back head is provided with a series of slots 12 adjacent its periphery. At 13 is an inner drum which is provided with a back head 14;, this back head being spaced slightly from the back head 11. In order to hold these two heads in proper relation there is provided a centrally disposed bolt 15 and on this bolt is pivoted a damper plate 16, the plate thus being held between the two back heads 11 and 14. The plate 16 i is provided with a series of slots 17 similar to the slots in the back head of the outer end and adapted to register with said slots when the plate is rotated to the proper position. In order to rotate this plate the latter has secured thereto a linger grip 18 which ,rejects through one of the slots 12, the 1 pecilie slot being provided with recessed portions 19 at the ends to permit the full movement of the plate 16. By means of this linger grip the plate 16 may be rotated on its pivot so that the slots 12 may be opened to any desired degree.

The space between the front ends of the" drums 10 and 13 is closed by means of a permanent annular closure 20, this closure being imperforate. Secured to the closure 20 by means ol a hinge 21 is a door 22 which serves to close the front end oi' the inner drum. Adjacent one Side of this door, preferably directly opposite the hinge 21, is a turn button 23 which is adapted to engage a keeper 24 so that the door, when closed, may be held in closed position.

Uppositely disposed stove lpipe connections 25 are provided in the outer drum and it is preferred that these connections be arranged vertically with respectto each other so that the hot gases rising through the lower ot the connections will pass evenly around both sides of the inner drum and out of the upper connection 25.

By means of the damper plate 16 the temperature of the inner drum may be regulated, the slots 12 being opened when it is desired to cool the inner drum and closed when it is desired to have the inner drum as hot as possible. Furthermore, when the slots are fully opened a small scraper may be employed to dra-w the accumulated soot out of the drum or to push it down through the lower stove pipe connection, as may be desired.

There has t-hus been provided a simple and etlieient device of the kind described and for the purpose specified.

Having thus described the invention, wha is claimed as new, is

1. In a device of the kind described, an outer drum having a tiXed back head provided with a series of slots adjacent its periphery, an inner drum having a back head slightly spaced from the back head of the outer drum, a centrally disposed bolt connecting said heads, a damper plate pivoted on said bolt and having a series of slots similar to the slots in the back head of the outer drum and adapted to register therewith, and means projecting through the outer drum to rotate said damper on its pivot.

2. Tn a device oi the kind described, an outer drum having a fixed back head provided with a series of slots adjacent its periphery7 an inner drum having a back head ends of said drums, a swinging door for tho slightly spaced from the back head of the front end of the inner drnn1,-and stove pipe outer drum, a centrally disposed bolt conconnections oppositely disposed intermediate necting said heads, a damper plate pivoted the ends of said outer drum.

5 on said bolt and having a series of slots In testimony whereof, I atlix my signal5 similar to the slots in the hack head of the ture7 lin presence of two Witnesses. outer drum and adapted to register there- JOHN B. PASCHE. With, means projecting through the outer Titnessesz drum to rotate said damper on its pivot, a YV. S. L. PEARCE,
